Unable to execute OIDC flow : The required parameter: [code_challenge] was not found in the request.
Hi All,
We are replacing our SAML authentication with IBM OpenID authentication service.
We created the form and initially we were able to authenticate without code challenge. But it is failing when the code challenge is included in the service.
"Unable to execute OIDC flow : FBTOAU202E The required parameter: [code_challenge] was not found in the request."
We don't have this field available on the OIDC form. Does anyone implemented OIDC authentication service with code challenge?
Refer attachment for screenshot of parameters required for OpenID.

@KiranKS I see that the support ticket has been closed.
Currently there is no way around in using PKCE during OIDC sso flow. The feature for PKCE in OIDC flow will be implemented in future releases (FDBK-113686)
GCS also assisted in setting up OIDC and the issue was resolved.
